So, in short, the birivas were tropeiros, or rather the descendants of the tropeiros and bandeirantes and inhabited the Campos de Cima da Serra region. The birivas were easily distinguished from the gauchos of the campaign and border, due to their appearance, which was already more mixed. I found 3 origins for the term biriva. The first comes from Biribá, the fruit of the biribaseiro, from the Tupi Mbiruya, which is a fruit similar to an ariticum, nona or count fruit. The second comes from another Tupi term mbi'ribi, which means small, little. The third is that biriva refers to a plant that was very common in the forests of the mountain plateau and as the biriva were men who inhabited this region of the forest, they received this name. I found a lot of references to the birivas as 'bush' people, mainly in mentions referring to those said by the gauchos in the campaign. Well, we know that the pampa is an open field, while the fields above the mountains are regions with more rugged relief and dense forest. It is worth noting that the term biriva was not used in a pejorative way. It was honorable to be called biriva precisely because they were courageous, fearless peasants who did a lot of hard work. The Birivas are distinguished from the Pampean gaucho because their hue is different and their daily work shaped them that way. They are different in the methodology of their rural work, in how they saddle the horse, in the way they speak, in the way they sing, dance, feed and even in their costumes. The main activity of the birivas was mule trampling. To give you an idea, they traveled an average of 25 km per day, with animals carrying up to 100kg of products in baskets and baskets. These mules were driven by shouts and whistles and the complete journeys reached 2,500 km. These wild trips had the purpose of supplying the center of the country with mules and other animals, mainly for the Sorocaba Fair, which was the main market. Just take a look at this map here with the main routes that the drovers took. It was the ground they were walking on, right?! And on these troop paths, several cities were born and to this day carry Biriva DNA in their streets and in their people. These cities were usually troop landings, where the drovers spent the night. And then you know how it is, a little shop appears here, another there, in a few years the town is built and so on. Because they had a unique job, the birivas presented very unique costumes and were full of influences as they traveled a lot and had contact with a lot of people. But basically the costume of the birivas tropeiros was composed as follows: On the head were felt or straw hats with a crown and wide brim, attached to the chin by chinstraps; Loose-fitting scarves around the neck; They wore a shirt and a vest, which is like an open, shorter coat or a vest. On top Poncho and flap for protection against the weather; They wore long johns and chiripás attached by a guaiaca and generally this guaiaca had a lot of pockets and were well stuffed. On their feet they had boots, but longer ones, almost of the Russian style, which came up to the thighs to protect them from the cold and wet. And they wore spurs with Nazarene rosettes. From the biriva costume, the main inheritance that was established in the current Gaucho clothing was without a doubt the guaiaca, which emerged with them due to the need to carry the planes together. And the guaiaca was stuffed because they generally carried money to do their business in addition to always being armed, with machetes, clubs, garruchas, as they were always on the road and we know that at that time justice was on their shoulders, right? As the birivas practically lived on the road, posing in camps among the village and without sweet female presence, as the work of drovers was a physical, tiring and very exhausting task. And when the birivas stopped to rest for a while, next to a fire, between a roast, a carretiro, scrambled beans and a few glasses of wine, there was always someone with a guitar for them to sing and also dance. And the dances that are of Biriva origin were dances where one pawn challenged the other to show who was more skilled. That's why things they had nearby were used, such as machetes, clubs and tap shoes. And it was Paixão Cores that rescued these dances, which are: The fandango tap dance, the Chico do Porrete, the Dança dos Facões and the Chula. So, as we can clearly see, the birivas were very important for the development of southern Brazil between the 17th century and the beginning of the 20th century, as they led the troops that transported the wealth produced, in addition to having influenced the emergence of several cities throughout the troop paths.
